The main problem with wheat immunity to leaf rust is the loss of efficiency of most Lr-genes. The decrease in efficiency is associated with microevolutionary processes within the variety and the emergence of new virulent races of the phytopathogen, which are able to overcome previously effective resistance genes. The article deals with the results of a phytopathological test and ana-lyzes winter wheat breeding material for resistance to leaf rust (Puccinia recondita Desm). The ob-ject of research was ten varieties of different ecological and geographical origin. With DNA mark-ers in winter wheat cultivars, no effective genes Lr9, Lr19, Lr24/Sr24, Lr41 and Lr47 and the ineffec-tive gene Lr20 were found in Russia. The combination of the Lr34 gene with ineffective genes could provide an increase in the level of field resistance of wheat varieties. In the cultivar List 25, the gene for age resistance Lr37 is assumed, which is partially effective in Russia. According to the results of a comprehensive assessment of winter wheat cultivars to leaf rust, a resistant type of reaction (R) was shown by the cultivars Zhiva (Lr1, Lr3, Lr10, Lr26, Lr34) and List 25 (Lr1, Lr3, Lr37); susceptible type of reaction (S) in the Malvina variety - (Lr1, Lr26), Solara (Lr1, Lr34), Etude - Lr3. Genes in various combinations are capable of providing field resistance of winter wheat to leaf rust. Most of the varieties were moderately susceptible to the disease.
Key words: brown rust, winter wheat, resistance, resistance genes.

The article presents the results of studies of the influence of various types of microelement chelated fertilizers on the formation of the yield of spring soft wheat variety Arkhat during presow-ing seed treatment. It was found that only treatment of seeds with Cytovit contributed to an in-crease in the size of the head by 17.7%, and when using other microelement fertilizers, it was at the control level. It was found that the increase in the number of kernels when using Gumostim and Multipurpose Siliplant in relation to the control was 8.5-10.4%, and more kerneled heads were ob-tained when using Cytovit, which provided an increase of 19.3%. With endogenous treatment of seeds with Cytovit, the yield of kernel from the head increased by 21.7% compared to the control. The highest kernel yield was obtained when seeds were treated with Cytovit, the increase to the control was 0.98 t/ha or 22.4%. The effectiveness of Gumostim and Multipurpose Siliplant was twice as low. The weight of kernel when using EcoFus, Gumostim and Cytovit increased by 7-12 g/l. There was no significant effect of microelement fertilizers on the change in kernel consistency. On average, over the years of the experiment, the weight fraction of crude gluten in the variant with seed treatment with Cytovit was 4.5% higher than the control variant. A positive effect of EcoFus, Gumostim and Multipurpose Siliplant on the accumulation of wet gluten was noted, the increase to the control was 1.3-2.8%. The advantage in this quality indicator was in the variant with Cytovit treatment, the weight fraction of wet gluten was 4.5% higher than the control variant. However, with an increase in the amount of wet gluten, a regular decrease in its elastic properties was noted.
Key words: wheat, micronutrient fertilizers, head, kernel, productivity, weight, gluten.

The relevance of the study is due to the fact that in accordance with the Decree of the Presi-dent of the Russian Federation dated 02.07.2021 No. 400 "On the National Security Strategy of the Russian Federation" one of the key factors determining the country's position in the long term is the ability to ensure technological leadership. The state of science and innovation are becoming key indicators of the state's competitiveness. One of the priorities of scientific and technological development is the creation of genetic technologies. Within the framework of the national project "Science" and the Federal Scientific and Technical Program for the Development of Genetic Tech-nologies for 2019-2027, three world-class genomic centers were formed, where the head scientific organization is the Kurchatov Institute [1-3]. The main task is the creation of new genetic lines of wheat, barley and potatoes with the desired properties, the development of genetic technologies for the creation of new producer strains for industrial biotechnology. However, despite the urgent need to develop innovative activities in the agro-industrial complex, agribusiness entities do not seek to introduce various innovations, including genetic technologies. According to experts, the lack of desire of agro-industrial complex enterprises to introduce new innovative products lies in the non-obviousness of the economic benefit from such long-term expensive investments, as well as in the absence of a trained qualified base of specialists ready and able to bring an innovative product to the stage of its implementation and commercialization on the market. There is a need to form a mechanism for the prompt implementation of innovations in the field of genetic technolo-gies in agro-industrial production, including through the involvement of industrial (technological) partners [4].
Key words: technological innovations, genetic technologies, industrial partners.

The results of five-year research under the soil and climatic conditions of the Middle Volga region show that the complex application of agrochemicals (liming + phosphorite application + NPK for the planned 4 t/ha of the spring wheat grain yield) increases the accumulation of dry mass of crop-root residues from 1.44 to 2.37 t/ha (by 64 %), improves mineralization of organic matter by 10.1 %, enhances the formation of structural units and compensates the removal of nutrition elements. On average, over five years, the combined use of the three above-mentioned agrochem-icals provided 3.77 t/ha of high-quality spring wheat grain, which is 94.3 % of the planned yield.
Keywords: liming, phosphorite application, mineral fertilizers, yield, spring wheat.

In a number of cases, such as unfavourable weather conditions during the ripening period, the production need to organize an earlier start of harvesting, stimulation of grain ripening on side shoots to produce seeds with less maternal variety, it is necessary to physiologically accelerate the ripening of plants without reducing their productivity. In this connection, the technological method of senication is used. The aim of the research is to study the effect of senication on changes of grain ripeness and to prove the optimal concentration of the working solution, which provides a high yield of seeds at different levels of mineral nutrition. The working solutions of ammonium nitrate in the amounts of 10, 20 and 30% were used as a senicant + 1% working solu-tion of 2,4-D ester. The crops were treated on three mineral nutrition backgrounds. As a result, it was found that senication of winter wheat crops regardless of the year and level of plant nutrition increases physiological ripeness and accelerates seed ripening. The treatment of plants with 20 and 30 % ammonium nitrate solutions and 1 % of 2,4-D ether provides a high average daily loss of moisture and increases the mass of 1000 seeds. Grain yield was consistently high when the plants were treated with 20 % ammonium nitrate solution + 1 % herbicide solution (2,4-D ester).

The application of mineral fertilizers in crop cultivation technologies ensures an increase in yield and product quality. However, there is insufficient information in the scientific literature about the varietal reaction to the application of mineral fertilizers, which can be successfully used in seed production and breeding. The purpose of the research was to evaluate the productivity and sowing qualities of seeds of winter triticale varieties, depending on the level of mineral nutrition. A two-factor field experiment was set, in which the reaction of ten varieties was studied on two agricul-tural backgrounds. As a result of three years of research, it was found that application of split mineral fertilizers (N 32 P 32 K 32 + N 30 + N 30) provided an increase in the yield and seed yield by 26-95%. The varieties Bereket and Tulus turned out to be the most responsive to this agricultural technique. The payback of one kg of fertilizers, applied during the cultivation of these varieties, was 23.7 and 19.5 kg of seeds (for other varieties, this indicator varied between 7.5-13.1 kg). The varieties Beta and Ataman Platov were the least responsive to the use of fertilizers. Sowing quali-ties (germinating power, laboratory germination, thousand-seed weight, growth power and morpho-logical characteristics of seedlings) were higher in seeds of all varieties grown with split fertiliza-tion. That was especially evident in conditions of increased moisture during the ripening of grain.
Keywords: triticale, variety, mineral fertilizers, seed productivity, seeds, germinating power, laboratory germination, growth power, seedling

Various devices built on the basis of existing methods for distinguishing types of printed text images make it possible to distinguish between the configuration of letters and digits in only one font. The inventive device introduces printed characters from a carrier into a rectangular matrix consisting of elements of a personal computer memory device (PC). On the basis of the devel-oped technique a PC software was created, according to which the image of each printed image from the starting point, is outlined in certain directions of parts of the image figure. The code of the printed figure is generated in the form of a series of directions. In this case, non-decisive di-rections are thrown out of the code and only a number of decisive directions are left, which carry the necessary information about a certain printed image. For this series, the configuration of the print letter or digit differs among the other configurations. The possibility of optimizing the soft-ware for PC, implementing the created method of distinguishing images of printed letters and dig-its is considered. The new device makes it possible to distinguish types of printed images of dif-ferent fonts, despite certain changes in the position of the elements of the shape of the image, their dimensions and the presence of certain defects in the printing

The materials of the article are devoted to the topical subject - improvement of quality of grain crops sowing. It is noted that the known designs of tine and disc coulters have significant traction resistance, form a wide furrow, which is difficult to cover, do not provide high-quality rep-lication of the field topography. All this negatively affects the uniformity of distribution of crop seeds, both on the length of the row, and on the depth of seeding. The most promising way to improve the quality of performance of the seeding unit is to equip grain planters with combined coulters. The article offers the design of the coulter with copying wheel of a pneumatic sowing machine for sowing the seeds of grain crops, it has a new design of the coulter disc and mecha-nism of adjustment of seeding, thus the disc has a conic form for stable forming a furrow, from inside of the disc a copying wheel is set on the axis, it is made of elastic material, playing the role of the disc scraper and regulator of the depth of seeding. The analytical dependencies allowing to determine the radius of soil element rn=0.025 m, the minimal sowing depth which was 0.02 m and the minimal radius of copying wheel rk min=0.096 m were obtained.
Keywords: grain seeder, theoretical studies, coulter with a copying wheel, sowing depth, seed distribution, soil.

The article presents laboratory studies of the issue of improving the qualitative indicator of sowing grain crop seeds, such as the uneven distribution of seeds along the length of the furrow by the experimental coulter of a grain drill with a hinged connection of the seed guide tube and soil disrupter with the body of the coulter. Using a laboratory setup, studies of an experimental coulter of a grain drill with a hinged connection of a seed guide tube and a soil disrupter with a coulter body were carried out to find rational values of its design and operating parameters neces-sary for high-quality work. Dependences' diagrams of the uneven distribution of seeds along the furrow length by the coulter of a grain drill with a hinged connection of the seed guide tube and the soil disrupter with the coulter body are obtained. The work presents two-dimensional cross-sections of the dependence diagram. They characterise the unevenness of seed distribution over the furrow length when a coulter of a grain drill with a hinged connection of the seed guide tube and soil disrupter with the coulter body works. These graphs show the dependence of the seed unevenness indicator on the oscillatory amplitude of the disturbing force acting on the soil dis-rupter, as well as the deformations of the plate spring. These deformations provide the least une-ven seed distribution over the furrow length.

Typical technologies of diesel engine breaking in with the use of break in and brake stands have a number of technical, economic and environmental disadvantages that make it difficult to use them widely. It is suggested to use the technology of cold breaking in of diesel engines with increased load-speed modes is proposed, the computational and theoretical justification of the breaking in modes and experimental studies. The technology of cold breaking in with increased load-speed modes has been developed. Theoretical substantiation of cold breaking in modes with increased load-speed modes and bench tests of the D-240 diesel engine in the studied modes were carried out. Experimental studies have shown the possibility of cold breaking in with in-creased load-speed modes by increasing the speed of the crankshaft and the intake air pressure for a certain time. For cold breaking in of the D-240 diesel engine according to the proposed tech-nology, six steps of breaking in are proposed with an increase in the rotational speed to 2200 min-1 and the intake pressure to 0.157 MPa for 35 minutes. Carrying out cold breaking in with increased load modes allows to create load-speed modes at additional steps, similar to the steps of hot breaking in under load.
Keywords: diesel, overhaul, cold breaking in, running in, load-speed mode.

An increase in the rate of milk production based on an increase in the milk productivity of cows is the main task of dairy cattle breeding. A reserve for the growth of milk productivity is the use of milking equipment that most fully meets the physiology of animals. An analysis of the de-signs of existing milking machines led to the conclusion that one of the main drawbacks is their extremely harsh effect on the teat nipple receptors and, accordingly, inhibition of the milk ejection reflex, which leads to a decrease in the intensity of cow milking and a decrease in milk yield. It has been established that the most important element of the milking machine is the teat cup liners, which are in direct contact with the animal. The research is based on the well-known principles of fluid (gas) and solid mechanics, the theory of elasticity and resistance of materials, as well as mathematical analysis. An equation for the maximum radial deflection of the liner barrel of the milking machine has been obtained, which makes it possible to determine the relationship between deformation and the mechanical characteristics of the material used, the main design and dynamic parameters. The simulation of the operation of the teat cup liner of the milking machine confirms the existence of a wave effect of squeezing out in the collapse phase.
Key words: teat cup liner, barrel, radial deflection, simulation, squeezing.

In recent years, more and more areas of agricultural land have been cultivated with the valua-ble non-traditional fodder crop Eastern galega (Galega orientalis Lam.), which perfectly combines high productivity with excellent fodder values and sustainable seed production, rationally uses agro-climatic conditions of the zone and increases soil fertility, and is valuable as a forecrop and a honey-bearing plant. Eastern galega sowing material contains 50...95 % of seeds with hard shell. Seed hardness is explained by impermeability of seed shells to water and air. To increase seed germination, reduce the seed rate of galega to 2.0 mln/ha and maintain the density of the grass stand, the seeds of a perennial legume fodder crop - Eastern galega should undergo pre-sowing treatment - seed scarification. The article presents the design and operating principle of the devel-oped scarifier SS-0,5, the technological scheme of which is based on the following technical solu-tions: a screw pipe with a transition to a four-section distributive rotating working body is used for transportation from the charging bunker; for seed treatment (cracking and scratching) a scarifying surface in the form of a stationary disk with an abrasive surface is used in the working chamber. The developed scarifier of seeds of leguminous crops SS-0,5 of a disk type qualitatively carries out technological process of scarifying of Eastern galega seeds. At an optimum supply of 0.5 t/h, the quality indicator of seed scarification of eastern galega reaches 98.8 %, seed damage - 0.6 %, which corresponds to agricultural requirements.
Keywords: forage crops, non-traditional, Eastern galega, seed hardness, seeds, scarifier, scarification, disc, working body, conveying, scarification quality, germination.

Preparation of qualitative mixed fodders-concentrates in conditions of small cattle-breeding enterprises in many respects depends on the chosen operational scheme of manufacture and cor-rect choice of the process equipment. The review analysis of existing technological lines of prepa-ration of fodder (fodder-medicinal) mixes, with establishment of the list of obligatory operations, and the required nomenclature of technical means is carried out. The technique of researches pro-vides the review analysis of technological lines of feeding shops applicable to small animal-breeding enterprises with a possibility of preparation of fodder-medicinal mixtures and disinfection of the damaged grain components. When detecting pathogenic bacteria in the processed fodder, the necessity of thermal treatment of components appears. However, due to the high cost of technological equipment this operation is not carried out. On the basis of the studied material we propose the operational scheme allowing to carry out thermal treatment with the use of disinfection equipment. In this case, the use of continuous mixers does not allow to distribute the micro-components accurately throughout the volume with respect to the formulation of the mixture due to the large error of the dosing devices. Stepped mixing is effective for the highest-quality mixing of components with a small fraction in the formulation. Relevant conclusions on the application of the operating scheme and the type of technological equipment are given.
Keywords: mixed fodder, grain, mixed fodder concentrates, purification, filling, heat treat-ment, milling, batching, mixing, technological scheme, operation, fodder-medicinal mixtures.

Currently existing in the world market machines for pre-sowing treatment of cereal seeds with protective and stimulating agents are equipped with loading and unloading devices of mechanical type, which strongly traumatize seeds, reducing their reproductive qualities. The aim of the re-search is to increase the yield and quality of grain by preserving the reproductive qualities of the seeds by reducing the traumatization during pre-sowing treatment. The research was carried out using general scientific and special methods, developed private methods, as well as known provi-sions of agricultural mechanics, gas dynamics and the theory of pneumatic conveying. On the ba-sis of the analysis of existing in the world market seed dressers, scientific researches and devel-opmental works, results of patent search, a promising direction for improving the technology of seed pre-sowing preparation of cereal crops in the conditions of agricultural enterprises on the basis of application of a seed dresser equipped with a pneumatic type grain loader has been re-vealed.A new design of pneumatic-loading device for mobile seed dressers of cereal crops, providing the reduction of traumatization, is proposed. The basic design and technological param-eters of a pneumatic seed pipeline, an unloader and a fan, which form the basis of the new pneu-matic-loading device, are substantiated. Methodical prerequisites for calculation of the pneumatic system of the pneumatic loading device are given. The results of the performed researches can be used by agricultural producers, agricultural machine building enterprises, as well as by research organizations and scientific workers when developing new and improving the existing technologies and technical means in agriculture. On the basis of the obtained results, work on creation of a new seed treater of cereal crops based on pneumatic loading of seeds with simultaneous separation of dust in a single continuous air stream has begun, which, along with the reduction of damage, will improve the quality of their treatment, will reduce the consumption of expensive preparations and costs of energy-intensive works on cleaning seeds from dust on grain-cleaning machines, which take place in existing technologies.
Keywords: dresser, grain crops seeds, grain damage.
